And ‘phalanx’ is short for phalanges, which are the bones in the hands and feet of most primates. The P3 is one of four bones in the toe (if you will) of the horse. Its function is to serve as part of the team which enables shock absorption in the entire hoof during weight bearing and while in motion.
What animals have phalanges?
The phalanges /fəˈlændʒiːz/ (singular: phalanx /ˈfælæŋks/) are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones.

Why do horses no longer have toes?
Horses, humans, and all other mammals share a common ancestor–with five toes. So how did horses end up with single-toed hooves? Over millions of years, many horse species lost most of their side toes. The middle toe evolved into a single large hoof, while the other toes became smaller and ultimately functionless.
Why do horses not have toes?
